单击侦听器到 RecyclerView [重复]

Question

我想要完成的是为 RecyclerView 行内的ImageView 创建一个侦听器。

这段代码已经可以工作了，但这不是我想要的解决方案，因为您需要双击ImageView才能获得所需的结果。

// row click listener
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getApplicationContext(), recyclerView, new RecyclerTouchListener.ClickListener() {

    @Override
    public void onClick(View view, final int position) {

        ImageView viewContent = (ImageView)view.findViewById(R.id.btnViewContent);
        ImageView deleteContent = (ImageView)view.findViewById(R.id.btnDeleteContent);

        viewContent.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "VIEW CONTENT", Toast.LENGTH_SHORT).show();
            }
        });

        deleteContent.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(), "DELETE CONTENT", Toast.LENGTH_SHORT).show();
            }
        });

    }

    @Override
    public void onLongClick(View view, int position) {}

}));

知道如何将其转化为单击解决方案吗？建议甚至是一条评论都会对我有很大帮助。

Answer 1

这不是我们的一位朋友建议的正确方法 onBindViewHolder 在滚动过程中一次又一次地被调用，因此在此处添加侦听器不是最佳做法。

最好的方法是按照我的建议将它添加到 ViewHolder 上。检查我上面的答案。

在 OnBindViewHolder 方法中添加你的 imageView 点击监听

@Override
public void onBindViewHolder(@NonNull final MyViewHolder holder, int position) {

    holder.btnClassAddCart.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // Do what you want here
        }
    });

}

Then there is no need to implement recyclerView.addOnItemTouchListener ,  inside Viewholder just add clicklistener on the view(image) you want below is the example for reference.

 ` public static class HeaderViewHolder extends RootViewHolder {

        @BindView(R.id.cardview)
        CardView cardview;
        @BindView(R.id.main_container)
        LinearLayout main_container;
        @BindView(R.id.music_cardview)
        CardView music;
        @BindView(R.id.shabad_cardview)
        CardView shabadvaani;
        @BindView(R.id.news_cardview)
        CardView news;
        @BindView(R.id.donate_cardview)
        CardView donate;
        @BindView(R.id.bs_cardview)
        CardView bs;
        @BindView(R.id.bl_cardview)
        CardView bl;
        @BindView(R.id.bng_cardview)
        CardView bng;

        @BindView(R.id.more_cardview)
        CardView more;

        @BindView(R.id.vid_cardview)
        CardView vid;

        @BindView(R.id.medi_cardview)
        CardView medi;
//
//        @BindView(R.id.ama_cardview)

        public HeaderViewHolder(final View itemView,final OnItemClickListener mOnItemClickListener) {

在 OnBindViewHolder 方法中添加你的 imageView 点击监听

    @Override
    public void onBindViewHolder(@NonNull final MyViewHolder holder, int position) {

        holder.imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // Do what you want here
            }
        });
}
